What exactly can we manipulate for DNA file in runtime with that "Keep DNA After Initialisation"?

What exactly can we manipulate for DNA file in runtime with that “Keep DNA After Initialisation”? We could not find any information about it except that it is giving a chance to manipulate in runtime.

Just the options we can see in the screenshot/in the documentation here https://dev.epicgames.com/documentation/en-us/unreal-engine/API/Plugins/RigLogicModule/UDNAAsset or something else?

Example: we have a set of poses so RBF and Twist/Swing are in that DNA exported, do we have access to those data to change some of them with an anim curve if needed? If for example in a specific animation we need to push more/less one or some of the poses or if we want to change some twist/swing values

or instead of controlled by curve, could we add an extra cases for the RBF in the DNA but triggered in specific cases ?

Thank you,

Emil
